Abstract (en)
An auto ranging system for causing an instrument for determining the frequency of a wave to be in a frequency mode or a period mode in response to the digits of the frequency of the wave determined in a trial interval is described. The cycles of the wave during which the cycles of an oscillator are counted during a period mode can also be selected from an examination of the digits.
